Specification of Letters Patent No. 10,346, dated December 2C, 1853.

To all whomy t may concern:

Be it known that I, ELIAS UNGER, of Dayton, in the county of Montgomeryand State of Ohio,- have invented a new and useful Improvement inMachines for Dressing Timber for Cabinet Purposes; and I do herebydeclare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to theannexed drawings, forming part of this specification, in which- Figure'l, is a perspective view of the machine. Fig. 2, is an end elevation ofthe same. Fig. 3, is a plan of same. Fig. 4, is a face view of theclamp, `for dressing broad surfaces. Fig. 5, is a bottom view of thevsame.

Similar letters of reference in the several figures denote the same partof the machine.

My invention refers to improvements in machines for dressing timber forcabinet purposes, and particularly to its adaptation to the tapering ofsuch timber and fashioning it so as to possess a cross section of anoctagonal or other polygonal shape, such as the form usually given tobed posts.

It consists in the employment ofl a slotted table carrying standards forholding' timber in the desired position, while the table is movedlongitudinally so as to bring the material against the cutters 0f arotary face plate; .the standards being furnished with eccentric pointsfor securing the timber at the proper angle for the dress required.

In the drawings a is the slotted table movable longitudinally upon theways r, by means of belting from the shaft t. In the slot ZJ of thetable e are inserted the 'lower portions of the standards or carriagesf,

which traverse the slot and are secured atV any point to accommodate thelength of timber, by wedges through the lower portions of the standardsor carriages, or in any suitable manner. The face plate is representedby c; it is revolved upon the shaft (Z by means of the belt g from thepulley w, and is susceptible of a lateral motion by reason of the framein which the shaft (l rests beingl movable bythe lever 3]. The faceplate is provided with two or more cutters, vinserted and acting in theusual manner. In the heads of the standards are the movable blocks ghaving on their faces the eccentric points c', i, the latter workingwith a thread in the block, and moved by the crank w; the blocks areheld in position by the set screws Z. yMovable-upon the table a is thesecurin )late it in which is theV shaft m carrying the cam n, andmovable by the lever j; the upper edge of the cama is perpendicular tothe face plate c which furnishes the means of accurately squaring thetimber dressed.

The operation of my improved machine is as follows: The timber to bedressed is lirst secured between the standards; in the case of bedposts, the dressing of which forms one of the most important uses of themachine, the original centers upon which they shall be perpendiculary tothe edge of the,

cam. The face plate c is brought into position by a movement of thelever y, and the table a moved forward by belting from the shaft` t, orany other well known device for producing a reciprocating motion of thetable; this brings the post against the 'cutters of the revolving faceplate and com-l `pletes the dressing of the same as requiredr A scalemay be formed on the inner face of sfo the standards for graduating themovement of the blocks g, so that the proper position may be given tothe post each time it is adjusted for `dressing.V\r7hen used fordress`ing the squares of posts, the opposite'points the table. The board issecured between the" teeth p and being parallel to the face plate` 0 isdressed as above described.

This.` machine which is. intended for the A yuse of cabinet makers, isof great advantage in the manufacture of bedsteads, by reason enablingthe operator to performwith eX- pedition and ease a species of laborwhichy by the-ordinary mode wastediousand frequently inaccurate.

of the eccentric points and the adjustability ofthe blocks in which theyareinserted; n .Y i

I do not claim` the movable table or the cutter may have any desiredangle With the revolving face plate, neit-her do I claim the axis of thepiece, for the purposes and in securing of timber between standards, asthe manner set forth.

such are Well known; but In testimony whereof, I have hereunto. j What Ido claim as my invention, and designed my name before two subscribingWiti5 sire to secure by Letters Patent, is` nesses.
